heya fellow GMC friendsive been trying for some time now to recordmic and instrument inputs on line6 toneport UX2 with reaperbut I cant find the options where you can select the lines 1+2 for micor 3+4 for instrumentstheoretically it should be possible to record line 1+2 and 3+4 on a seperate line each

Hmm I never used reaper but there must be such option..First you open two audio tracks and in its options you should have that choice..Also if not, check global preferences and I think you can assign left channel to 1-2 and right to 3-4 so you could than assign left/right channels to separate tracks and get different inputs that way..I hope someone with reaper installed will give you more precise info on this subject..
